CC -!- FUNCTION: Required for the development of the one-cell zygote and
CC endosperm in embryos (PubMed:15634699). Required for micropylar pollen
CC tube guidance, but has no effect on ovule development and gametophytic
CC cell fate specification. May connect transcription factors and the Pol
CC II machinery to regulate pollen tube attraction, via its interactions
CC with AGAMOUS-like (AGL) transcription factors, MEE14/CCG and the
CC Mediator complex (PubMed:26462908). {ECO:0000269|PubMed:15634699,
CC ECO:0000269|PubMed:26462908}.
CC -!- SUBUNIT: Homotetramer (PubMed:26462908). Interacts with MEE12/CCG,
CC MED7A, MED7B, MED9, AGL49, AGL53, AGL75, AGL80, AGL81, AGL82, AGL103
CC and NRPB1 (via CTD) (PubMed:26462908). {ECO:0000269|PubMed:26462908}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000269|PubMed:26462908}. Cytoplasm
CC {ECO:0000269|PubMed:26462908}.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Alternative splicing; Named isoforms=2;
CC Name=1; Synonyms=CBP1.1 {ECO:0000303|PubMed:26462908};
CC IsoId=Q9XIM0-1; Sequence=Displayed;
CC Name=2; Synonyms=CBP1.2 {ECO:0000303|PubMed:26462908};
CC IsoId=Q9XIM0-2; Sequence=VSP_058072;
CC -!- TISSUE SPECIFICITY: Expressed in roots, leaves, stems and flowers.
CC Expressed in the central cell of mature ovules.
CC {ECO:0000269|PubMed:26462908}.
CC -!- DISRUPTION PHENOTYPE: Disrupted function of the female gametophyte.
CC Defective in micropylar pollen tube guidance leading to zygotic
CC lethality. {ECO:0000305|PubMed:26462908}.
